Providing the first application for podded electric drives in the ferry market, July's arrival of the innov- ative RoPax vessel Nils Holgersson signaled a vibrant new phase of development of the busy Trave- muende/Trelleborg route between Germany and Sweden. The TT-Line project marries an advanced diesel- electric configuration with pragmatic requirements relating to operating efficiency, plant and power flex- ibility, cargo section design and environmental compatibility in the eco-sensitive Baltic trading regime.

Completed by the Bremerhaven yard of SSW Fahr-und Spezialschiffbau, the 34,500-gt Nils Holgersson is also notable for the arrangement of its multiple, main diesel generator sets within the vessel's double- shell structure rather than in a conventional engine room location aft.

Tycom Reliance

Keppel Hitachi Zosen t

Cableship

Keppel Hitachi Zosen Limited (KHZ) delivered its first cable laying and repair vessel to TyCom. Named TyCom

Reliance, it was designed to be the most efficient cable laying and repair ship in TyCom's fleet. KHZ was award- ed the first contract to build two cable laying and repair vessels for TyCom in April 2000. Subsequently, TyCom exercised its option to build an additional four sister ves- sels in November 2000. "The effective execution of the construction of TyCom

Reliance has been made possible through the application of new technology, creditable work put in by the design team, good project management skills and close partner- ship with suppliers, sub-contractors, classification and regulatory authorities and TyCom's project team," said Choo Chiau Beng, Chairman of KHZ. Fred

Hamilton, TyCom's vice president of International Construction, Operations and Maintenance, said, "We are receiving an excellent ship at a competitive price. This vessel will play an important role in the deploy- ment and maintenance of the TyCom Global Network in this region." At 12,130 git, each cableship is twin screw, diesel electric driven and dynamically positioned. Measuring 459 ft. (140 m) in length and 72 ft. (22 m) in breadth, the cableships are purpose-built for installation and maintenance of undersea fiber optic systems and are equipped with the latest in cable, navigation and safety equipment.

TyCom Reliance, the first in the series of six cable- ships Keppel Hitachi Zosen is building for TyCom, was named on August 1, 2001. This highly sophisticated purpose-built cableship was designed to be the most efficient cable laying and repair ship in TyCom's fleet of cableships in operation.

Smart Electronic

Level Switch with

No Moving Parts

The Sea Switch Two was designed and patented for all tank applications. The Sea Switch Two offers a reliable solution for liquid level detection and control for cargo, ballast, and storage tanks, without any moving parts.

The Sea Switch Two uses a fully static system that is based on the propagation of an acoustic wave into a metallic rod. A piezo-electric sensing element produces a wave along the rod. As the liquid reaches the sensing element the oscilla- tion stops and the alarm is activated.

The Sea Switch Two sensor detects high, high- high, or low level in any liquid with an alarm output given by a dry contact or current loop change 6-18 mA. • Easy installation • Self-test built-in • Fully static system - no moving parts s
