Maritrans Secures Patent for Converting Single-Hull Tank Ships

Maritrans Inc. has obtained a patent on its proprietary process for rebuilding single-hull tank ships and converting them into double-hull vessels. With the most recent patent, Maritrans has now patented the double-hull conversion process for both barges and tank ships. The U.S. Oil Pollution Act of 1990, as well as the International Convention for the Prevention of Pollution from Ships (MARPOL), each require the retirement of single-hull tank vessels. In January of 2001, Maritrans announced that it had received the first of three patents for internal double-hull conversions of single-hull barges. These Maritrans patents involved pre-fabrication of large tank structures that are inserted into the existing hull, with a trunk deck extending above the pre-existing deck. The design allows double-hull conversion while preserving virtually all of the previous cargo capacity. Maritrans is currently completing its fifth barge rebuilding project using this patented process. This latest patent, for single-hull tank ships, addresses the unique design of these vessels. Maritrans utilized its computer-assisted modular design process, pioneered in the previous double-hull patents, to formulate an appropriate double-hull structure for tank ships. The patent differs from the previous barge patents in that it combines the addition of an inner bottom with external side modules. Maritrans also has other U.S


USCG Codifies Single Hull Phase-out Requirements

In a notice of proposed rulemaking (NPRM), the USCG proposes to clarify and codify a policy it issued in April 1999 regarding phase-out dates for single hull tank vessels. OPA 90 includes requirements for double hull tank vessels and phase-out schedules for all single hull tank vessels operating in U.S. waters. Tank vessel owners are required to remove single hull tank vessels from service on a specific date, depending on such factors as the vessel's gross tonnage, age and hull configuration


ExxonMobil Still Chartering Single Hulled Tankers

U.S. oil giant ExxonMobil continues to charter single-hull tankers for its oil, tanker brokers said on Thursday. ExxonMobil has been in the market for a five-year time-charter since late August, brokers said, and has recently been giving serious consideration to a single-hulled very large crude carrier (VLCC) that will be nearly 20 years old by the end of the charter in 2005. Negotiations, however, have recently reached a stalemate, brokers said.
