community. The company, which has been family-owned and operated since its inception, now operates one of the largest shiprepair and conversion yards on the US East Coast, at its base in Charleston, South Carolina. Te facility offers three graving docks,

which can handle vessels up to Panamax in size. In addition to the docks, the facility also offers a number of enclosed workshops, ten 56tonne gantry cranes on a continuous rail system; two tower cranes; rail access; over 2400m of deepwater quay and a floating dry dock for smaller vessels. In early 2012 DSI was busy working


several Military Sealift Command (MSC) vessels as well as three further internationally-trading vessels for owners based in Canada, Germany and Norway. Loy Stewart Junior, president, says: “DSI has gained a good reputation with international ship owners and maintains a ship repair agency network around the globe that solicits projects for the yard. Te yard has now successfully drydocked over 50 international vessels, including ships from Germany, United Kingdom, Norway, Greece, Italy, Denmark, France, Cyprus, India, Japan and Singapore.” A notable MSC contract for DSI


involves the dry cargo/ammunition ship USNS Sacagawea. Some of the major work items during the drydocking include performing a generator overhaul; installing a reverse osmosis system, which

provides fresh water to the ship; making freezer deck installations; and inspecting and refurbishing the propeller shaft and stern. Tis project is expected to be completed by late February this year. DSI has also been awarded a significant


contract to work on the MSC fast combat support ship, USNS Arctic. Work will consist of conversion upgrades as well as ship class and certification-driven maintenance and repair work, during a drydocking. This contract includes options, which if exercised would bring the cumulative value of the project, which is due for completion in September 2012, to over US$27 million. Other upcoming drydockings include

slight slowdown. Overall DSI worked on more than 50 vessels in 2011, including offshore support vessels, vessels for MSC, US Coastguard and MARAD, commercial tankers, cargo and supply vessels, dredgers and barges. The company also completed the


conversion of the 46,000dwt shuttle tanker Overseas Chinook for OSG, in readiness for a charter with Petrobras. Tis follows on from an identical project to convert OSG’s Overseas Cascade in 2010. Both vessels were fitted with CP propellers and tunnel thrusters from Rolls-Royce, to provide the necessary control accuracy when manoeuvring at loading facilities and a bow platform, which included various hydraulic components. Te yard also installed a TT tunnel thruster, along with a Caterpillar- powered 2250kW generator set. One notable repair project carried out


by DSI in 2011 involved the 7450dwt containership Tropic Sun, which was damaged during Hurricane Irene. Te yard removed the bulbous bow, which had been virtually destroyed by the impact, and replaced it with a new one, amongst other repair works necessitated by the grounding. SRCT
