History of Bennett Offshore, 1997 to 2017

Added to the archive in 2026 · Reference note, not an original Bennett Offshore page

William T. Bennett, Jr. left his post as chief executive of Friede & Goldman in the spring of 1997 and opened a naval architecture and consulting practice under the name Bennett & Associates, L.L.C. For the first months he worked from his own house with one structural engineer. By the autumn he had bought a building on St. Charles Avenue in New Orleans that was close to a hundred years old, and the firm grew there over the next few years.

He was not new to the trade. The restored key personnel page gives his background: a Tulane graduate of 1963 in mathematics and psychology, not naval architecture (a route compared with today's in studying naval architecture), he worked offshore for a pipeline and construction firm, then in naval architecture and shipyard design, and joined Friede & Goldman as a project engineer in August 1974. He ran that company as president and chief executive from 1989 to 1997, when its work included self-elevating and floating production units for North Sea operators.

The pages restored on this site come from the last chapter of that story, roughly 2012 to 2017, when the company traded as Bennett Offshore and belonged to Keppel Offshore & Marine. This note fills in the chapters before and after, using the public record: the Wikipedia articles on the company and its best-known projects, and the company's own news pages preserved in this archive.

New Orleans, 1997 to 2005

A small office with a short client list does not usually get invited to Singapore. In 1998 Keppel FELS asked Bennett and his engineers to co-design a new jack-up drilling rig. The result became the Keppel "B-Class". The type sold well: a rig ordered by UMW Drilling in 2014 was the 75th B-Class unit ordered from Keppel since 2000. Bennett engineers also worked on Keppel's A-Class and N-Class jack-ups. In February 2014 Keppel Offshore & Marine gave Bennett its Gold Award for innovative engineering on the B-Class; by then, the archived news item says, more than 30 B-Class units were in the market. That early link with one shipbuilder explains most of what happened to the company later.

The next landmark was a floating unit. In 1999 Cal Dive International approached Bennett & Associates to complete the basic design of a semisubmersible, and later the detailed design as well. The original Q4000 concept came from SPD/McClure, which owns it; Bennett developed it into a buildable vessel. Richard Michel of Bennett & Associates and William Strong of Cal Dive presented the "Quantum 4000" in a joint paper at the Offshore Technology Conference in 2000. Keppel AmFELS built the vessel in Brownsville, Texas, for about $180 million, and the vessel entered service in 2002 with dynamic positioning on six azimuthing thrusters, a Huisman tower and an overall deck capacity of 4,000 tonnes. The restored Semisubmersibles page and the technical papers list show how the firm described the job itself.

The Q4000 came back into the news in 2010, eight years after delivery. During the response to the Deepwater Horizon blowout in the Gulf of Mexico, crews used it to position the containment dome and to attempt the "top kill", pumping drilling mud down its pipe into the failed blowout preventer. The top kill did not stop the flow. After a capping stack sealed the well on 15 July 2010, the Q4000 took part in the static kill, and on 4 September 2010 the failed blowout preventer was recovered onto its deck as evidence for the investigation.

Bennett's work was not limited to rigs. In 2004 CG Railway, which runs a rail ferry across the Gulf between the United States and Coatzacoalcos in Mexico, hired Bennett & Associates to add a second rail deck to its ferry Banda Sea. The conversion raised the ship's capacity to 115 railcars, and the firm also designed adjustable bilevel loading ramps for both terminals so that cars could reach the upper deck. The restored Innovations page tells the same story from Bennett's side and names two converted ferries, the Bali Sea and the Banda Sea, loaded through one articulated ramp.

The primer and the storm

In 2005 Bennett & Associates and Keppel FELS co-wrote Jack Up Units: A Technical Primer for the Offshore Industry Professional. They meant it as an introduction for people who work around jack-ups without designing them. Engineers started calling it "the jack-up primer", and the company gave it its own page, restored here at /primer.html.

The same year, Hurricane Katrina reached the Louisiana and Mississippi coasts in August. Levee failures left New Orleans without power and basic services for months, and the firm moved its staff to Houston. When utilities returned to St. Charles Avenue, the original office reopened, but Houston stayed on as headquarters. The company's own introduction, preserved here as the 2013 About page, says the headquarters is in Houston and the engineering office in New Orleans.

MinDOC and the Titan

MinDOC began as an idea from Alden "Doc" Laborde and William Bennett: a multi-column floating platform for deep water, meant as an alternative to a spar. In 2006 ATP Oil and Gas went looking for a drilling platform, took an interest in the concept, and gave Bennett & Associates a design contract. The unit became the ATP "Titan", which the company describes on the restored MinDOC page. According to the Wikipedia account, Titan was the first deepwater dry tree drilling and production platform built in the United States. "Dry tree" means the wellheads sit on the platform deck, not on the seabed, which makes later work on the wells easier.

Keppel ownership and the ORCA platforms

Keppel Offshore & Marine bought Bennett & Associates in January 2012 to add design and engineering depth to the group. The firm kept serving outside clients and renamed itself Bennett Offshore to reflect the larger role. The home page from 2016 put the arrangement in one line: the company stayed "a small, dedicated team of experienced engineers" with access to Keppel's construction support.

The main product of those years was a family of self-propelled, self-elevating platforms, the ORCA series, designed together with Keppel's Offshore Technology Development group. The range ran from small units sized for the Gulf of Mexico to large ones up to 115 metres long that could install wind turbines and foundations heavier than 800 tonnes. Operators could fit them out for construction support, light drilling, well intervention, plug and abandonment, coiled tubing work, wind farm installation, gas compression or accommodation. You can open each model on its restored page: ORCA 1500, 2500, 3500, 3500-WIND, 4500-WIND and 10000, with the series overview on top.

The archived news pages trace the first deliveries. Nakilat-Keppel Offshore & Marine (N-KOM), the Qatari joint venture yard, laid the keel of its first liftboat to a Bennett design in 2014 (keel laying) and showed the design, LB310, at ADIPEC in Abu Dhabi that November (ADIPEC). In July 2015 Keppel FELS took an order from Crystal Heights Holdings for a high-specification liftboat designed by Bennett with Keppel FELS (Crystal Heights). In February 2016 N-KOM delivered the first unit, Al Safliya, to Gulf Drilling International (Al Safliya). That May the Houston team supported Keppel FELS with engineering for a lift of Diamond Offshore's semisubmersible Ocean Apex on the FELS Can Do barge (Can Do).

After 2017

Archive snapshots from 2017 onward show a different home page titled "We have moved". It told visitors that Bennett engineering and consulting would now come through two Keppel companies: Keppel FloaTEC for deep water design, and Keppel LeTourneau for shallow water work, jack-ups and liftboats. Most inner pages stayed online in their old form into 2019, which is why this archive could recover them.

Keppel itself changed shape later. On 28 February 2023 Sembcorp Marine completed its purchase of Keppel Corporation's offshore and marine division, and in April 2023 its shareholders approved a new name, Seatrium. The old domain lapsed. Between 2023 and 2024 it carried unrelated spam pages, which this site does not reproduce.

Nothing here speaks for Bennett Offshore, Keppel or Seatrium. If you need the company's current design services, contact those groups through their own channels. If you want to know how a small Gulf Coast design office worked between 1997 and 2017, start with the company introduction and the key personnel page, then read the primer.
