Safetug I
Closed
The objective of this JIP is to identify the relevant modes of tug-terminal operation in the various operational contexts, to quantify the appropriate operability envelopes while assisting in waves, to quantify the operational effectiveness in waves, to identify the relevant criteria per type of the operation and to find the important factors in the design, equipment and operation.
Objective
The objective of this JIP is:
- to identify the relevant modes of tug-terminal operation in the various operational
- contexts,
- to quantify the appropriate operability envelopes while assisting in waves,
- to quantify the operational effectiveness in waves,
- to identify the relevant criteria per type of the operation and
- to find the important factors in the design, equipment and operation.
APPROACH
The commitment of all parties involved in the tug-terminal operations is seen as essential for the success of this JIP. Only through integration of the various technologies and practical experience combined with the envisaged knowledge extension in this JIP, the issues of tugs operating in waves around terminals can be taken forward. This required commitment is reflected in the proposed project organisation.

BACKGROUND
Tugs play an important role in the availability of terminals in ports and offshore. Terminals and offloading operations in general, are more often located in exposed areas (wind, waves and currents) or require tug assistance in the exposed approaches (escorting). However, at the same time downtimes of the related operations are to be kept to a minimum. The more effective and enduring tug operation in open seas will enable these lower downtimes. This requirement puts a larger demand on tugs and their crews as they have to assist vessels in exposed areas. Operators, in particular for LNG, require low downtimes combined with a safe operation, which can be achieved by proper (escort) tugs during (port) approaches. Equally important is the persistent operation of tugs in offshore circumstances during side to side, tandem offloading operations and future offshore offloading concepts where tugs are needed. In and around ports often escorting regimes are put in place to cope with emergencies or assist large vessels where speed control is important.
SCOPE OF WORK
It is proposed to split the project in three connected, partly parallel work packages (WP):
1. Tug-Terminal operations (WP 1)
2. Offshore Berthing & Escorting model tests and analysis (WP 2)
3. Tug Design Parameters (WP3)
