AUGUST 1, 2017 — In addition to all the cruise ship work for which it is well known, Grand Bahama Shipyard (GBS), the largest shipyard in the Caribbean, also carries out a large volume of work on a broad range of other commercial vessels.
In the first half of this year, the yard completed work on 30 non-cruise vessels, predominantly repeat business from U.S. East Coast, Gulf and Caribbean operators and transporters such as Crowley, OSG, Seabulk, Seaboard, Tropical, TrailerBridge and Tote and and including tankers, bulk carriers, containerships, tugs, dive support vessels and drilling support vessels.
Long-time customer Crowley Marine Services, Inc. will drydock over a dozen vessels in 2017. In January, GBS welcomed the Crowley-managed containership National Glory. In March, works were completed on Barge 750 followed by Tug Legend. Four Crowley vessels, Tug Coastal Reliance, Tug Ensign, Barge 550-4 and Barge Miami all visited in April. Tug Liberty and Barge 750-3′ were both in for their routine class surveys in May. Additional vessels from the Crowley fleet are planned for dry dock throughout the remainder of 2017.
Similar work in each dry-dock project involved hull, deck and cargo tank blasting, including the application of high performance coatings, while major technical projects including generator overhauls, gearbox overhauls, steel replacement in underwater areas, cargo tanks, ballast tanks. Pipe replacements was executed throughout and on multiple systems, electric motor overhauls and the support of the CPP propulsion system overhauls. Deck machinery items, including deck cranes, were also overhauled.
In Dry Dock No 3, OSG Overseas Longbeach was out of the water for 10 days. Highlights of the work included over 300 meters of pipe replacements, overhauls on 14 electric motors and the testing and cleaning of approx. 190 cu.m within 14 tanks in five days. Complete hull treatment and application of high performance coatings concluded the dry dock program.
Polska Zegluga Morska PP returned to the yard with two bulk carriers. Raba in followed by the San. Both were docked in the shipyard’s Dry Dock No.1 for propeller overhauls, minor engine work and seal renewals. The cargo holds received a comprehensive cleaning and coating. A major project on both vessels was complete hull treatment and application of high performance coatings.
Bibby Offshore Ltd. docked the diving support vessel Bibby Sapphire for an extensive 20-day work period in Dry Dock No. 1 in January. Works included: steel replacement, tank cleaning and disposal of sludge, electric motor overhaul, pipe replacement, bow thruster overhaul and while complete hull treatment concluded with the application of anti-corrosive coating followed by two full coats of anti-fouling.
First time visitors included the Chinese-owned research/survey vessel BGP Pioneer, managed by Thome Offshore Management, and companion tug BGP Supply II, which double dry docked on Dock No. 1 in February. Work completed to Pioneer included extensive pipe work and complete hull treatment.

BF Ship Management GmbH & Co KG’s containership BF Ipanema visited the yard in January for the overhaul of 29 shipside valves, renewal of ballast tank manholes, stern seal renewals and cosmetic polish of propeller blades. The hull was completely blasted using the yard’s UHP blasting equipment and owner-supplied coatings.
Columbus Ship Management’s container ship Monte Tamaro went into Dry Dock No. 3 in February for a 12-day work period. Works included the replacement of stern seals; removal of the propeller and blades. The rudder was removed for survey and was found to be in poor condition, resulting in the procurement and fitting of a new rudder which required the support of the yard machine shop with shaft machining to finished dimensions. The yard supported owner’s technicians with thruster overhauls. UTM gauging of the hull was performed to meet class requirements, on inspection of the results minor steel renewal was required. The hull was completely blasted using the yard’s UHP blasting equipment and owner-supplied coatings applied.
Dole Ecuador dry docked in late March for minor propeller repair.
Minerva Marine Inc.’s tanker Minerva Lydia berthed alongside the North Beach Pier for a two-week period in March to overhaul the main engine. This work was performed by the yard’s mechanics under the supervision of owner’s technical team.
In March, MSC returned to the yard with its containership Belle for minor repairs. The success of this project resulted in the award of the containership Michaela,whicht visited the yard for a week-long dry dock period in June for work that included extensive pipe repairs to piping systems in the engine room using approx. 55 meters of galvanized steel pipe that was replaced in four days. Hull treatment included full UHP blasting followed by anti-fouling coating provided by International Paint. The shipyard assisted owner’s appointed technicians with main engine and bow thruster overhaul, impressed current system overhaul and sea valve overhaul of approx. 50 valves.
