speed a vessel may proceed in a given thickness of ice. In addition it will determine the distance
the vessel is to be astern of the icebreaker escort, and will also determine the width of navigable
curvature of the channel in turns the ice breaker is to make.
The Ice certificate will also assess vessel suitability for operation in lower temperatures of Aniva
Bay.
7.6 Certificate of Engine Power
All tankers in winter are required to have a ‘Certificate of adequate engine power’ during the ice
season. This confirms that the tanker can achieve a speed of at least 4 knots in ice thickness of
60 cms following in the lead created by ice breakers in the absence of ice pressure. The
certificate is issued by an institute approved by the Russian authorities.
7.7 Propeller Tip Immersion
All tankers are to have a propeller tip immersion of at least 70 cms. LNG carriers are to have
a propeller that is the equivalent of the Russian ice class ‘LU2’. If this is not the case, there
may be a requirement to increase the propeller tip immersion. The required immersion will form
part of the Certificate of adequate engine power.
7.8 Winterisation
Winterisation is the requirement that the vessel, during the winter period, from November
to April, is able to operate in sub zero temperatures down to –25 o C, which may be experienced
within Aniva Bay.
Precautions include measures to ensure that the fire fighting equipment on deck is operational,
in particular that the fire lines do not freeze, that the ballast space air ventilators do not freeze,
and that the mooring equipment is operational. The cargo and ballast systems should be
protected against cold temperatures. The crew are to be provided with appropriate warm
clothing and the accommodation heating must be effective. Other measures will require the
deck steel to be of a grade that will withstand cold temperatures, and internal heating may be
required in the ballast spaces. Steam line dead end sections are to be treated with caution and
drained of condensate which may be susceptible to freezing.
A study of winterisation requirements by SEIC has identified the following requirements.
• Ice class for hull structure - Vessels, which are built with a view to load at Prigorodnoye
throughout the year, are recommended to be built to the Russian Ice Classification level 'LU2'
or higher. It is a SEIC requirement that all vessels have ice classification for the hull structure.
Although it is possible for a low or no ice class vessel to enter Aniva Bay SEIC does not
recommend this as the safe speeds could be severely limiting.
• Ice classification for propeller and propulsion shafting - Propeller and shafting are to meet the
requirements of the Russian Maritime Register of Shipping’s LU2 ice classification or
equivalent.
• Manifold - The OCIMF "Recommendations for Manifolds for Refrigerated LNGC" and SIGTTO
ship shore compatibility documentation can be used as guides. Recommend that a heated
manifold shelter be fitted on each manifold for use during loading operations. Means to keep
manifold clear of snow and ice to be provided.
• Winterisation - It is to be possible to operate the vessel in sub-zero temperature of -25°C with
