steer and stop a tanker in case of engine or steering failure or any other accident.
PKL Flote express a great concern about environmental issues regarding sea pollution and therefore we promote compulsory tug escort services in dangerous shore areas for loaded oil and chemicals tankers as an efficient and cheap pollution prevention measure. Please look at the statistics provided by HELCOM
and Maritime Accident Response Information System
Unfortunately a usual tug cannot be used for escorting services. Escort tug should have specially designed hull (to work with it as floating anchor in perpendicular with vessel's direction), special escort winch, and other equipment. To perform such services a tug should get special escort certificate from a classification society. PKL Flote today has two escort tugs.
Tug escort is already compulsory in several ports of the Baltic Sea in Finland, Sweden, and Russia.
HELCOM recommendations for escort tug requirements*:
The Gulf of Finland international waters approved escort tug shall have a DNV or
similar certification of fulfilment of the escort requirements. The vessel shall be
capable for direct and indirect escort operation modes so that it can:
The ice breaker/escort tug to be equipped with adjustable constant tension towing winches for the escort duties and
towing in ice.
- stop the tanker in case of a propulsion damage from 10 knots speed
in less than 2000 meters distance
- control the tanker so that in case of rudder being stucked in 35 deg
angle and main machinery being stopped the tug can stop the tanker
from 10 knots speed so that she will not drift aside more than 350
- escort the tanker into port through the archipelago lane together with
another escort tug: this means max draught of 7.0 meters
- carry out oil spill combatting operations if necessary
- carry out fire-fighting or rescue operations if necessary
