Prigorodnoye Export Terminal Port Regulations Rev 01 located at or near the bottom of the vessel to minimize the probability of ice clogging. It is recommended that vessels have a cooling Kingston Valve Arrangement - See IMO. • Ice resistant coating on waterline - The water line of the vessel from the laden to the ballast levels is to be coated with an ice resistant low friction coating. Inerta 160 paint is strongly recommended. Area covered at the forward end to be suitably extended. • Steel - The steel used in the main deck and upper sides is to be confirmed as having adequate toughness for operation in an ambient air temperature of -25°C or heating is to be applied to keep the surface temperature of the steel above -10°C with an external ambient temperature of -25°C. • Crew - To be provided with "Arctic" clothing and to be trained in cold weather precautions. • General piping and cabling - Maximum use to be made of the under deck passageways, trunk-ways, forecastle space, etc. for routing and installing piping, cabling and equipment, to minimise exposure to the elements. • Exposed fresh water piping - To be protected against freezing in outside air temperature of - 25ºC and wind of 20 m/sec by trace heating or running in protected areas. • Cargo system - Operation of valves, vents, gauges to be able to operate in -25°C with 20ms-1 wind speed. Heat tracing recommended. • Ballast system - The risk of ballast tank water freezing for the tanks of a 145,000 Moss type vessel is not considered to be great due to the short transit time in cold weather. SEIC however recommends an air bubbling system be fitted in the ballast tanks to reduce the risk of ballast water freezing. If no physical system is fitted then ullage is to be kept in the ballast tanks to enable the tanks to be raised in level prior to discharge. The vent pipes and heads are to be prevented from freezing and all valves and all exposed gauges are to be capable of operation at -25ºC and wind of 20 m/sec. • Fresh water and distilled water tanks - Measures to be taken to prevent freezing if to air and sea temperatures of -25ºC and -2ºC respectively. If necessary wing speed of wind of 20 m/sec to be considered. Heat balance calculations to be carried out. Vent pipe heads shall be protected by covers. Consideration to circulation systems to be given. • Diesel oil tanks - To be fitted with heating facilities having sufficient capacity to maintain a temperature of 10ºC at design air and sea temperatures of -25ºC and -2ºC respectively unless heat balance calculations show otherwise. If necessary wing speed of wind of 20 m/sec to be considered. Vent pipe heads shall be protected by covers. • Other fuel oil and lubricating oil tanks - Heat balance calculations to be done to show that tanks will not freeze at air and sea temperatures of -25ºC and -2ºC respectively. If necessary wing speed of wind of 20 m/sec to be considered. Tank vent pipe heads to be protected against freezing. • Other exposed tanks - Heat balance calculations to be done to show that tanks will not freeze at air and sea temperatures of -25ºC and -2ºC respectively. If necessary wind speed of 20 m/sec to be considered in design. Tank vent pipe heads to be protected against freezing. • Auxiliary machinery - Auxiliary machineries and their systems eg. D/G, Fans etc. to be operable and suitable for outside air temperature of -25ºC and wind speed of 20 m/sec. • Electric space heaters - Heating shall be provided for rooms such as the emergency generator and steering gear rooms to maintain a temperature of 3ºC at an outside air temperature of –25ºC and a sea water temperature of -2ºC with wind speed of 20 m/sec. All electric heaters are to be provided with independent high temperature overheat trips. Consideration shall be given to maintaining a temperature of at least 3 °C for spaces such as the laundries, dry stores and forecastle spaces. • Deck part heating requirement - Consideration to be given to heating of the deck stores, deck bunker lines and deck hydraulic lines. • Deck machinery - Deck cranes and stores cranes to be operable at -25°C and 20ms-1 wind speed. Recommend hydraulic lines to be heated and a sheltered heated cab fitted. Note hose handling cranes maybe used in ship to ship cargo transfer therefore essential that the hose handling cranes are suitable for low temperature operation.

Prigorodnoye Export Terminal Port Regulations Rev 01 equipment to be assured. • Mooring and anchoring equipment - Mooring equipment to be capable of operation at -25°C with 20ms-1 wind speed. Means to keep working areas and equipment clear of ice to be provided. • Fire fighting equipment - To be operable at temperatures down to-25°C with 20ms-1 wind speed. This includes the water spray systems. Consideration to be given to running systems in the under deck pipe passage, heating systems or continuously draining systems or the ability to drain and dry systems. Exposed spray nozzles to be heated. • Lifeboats - Lifeboats to be enclosed and heated. Quick release gear and lifeboat release to be confirmed as able to operate in -25°C with 20ms-1 wind speed. Consideration to be given to heating the access doors. Means to keep access walkways clear of ice to be provided. • Liferafts - To be insured that they can be launched in cold conditions. Release mechanism to be trace heated or assured of operation at -25°C. • Accommodation - Adequate heating system is to be provided when the ambient outside air temperature is -25°C and the wind speed is 20ms-1. Precautions to prevent ventilators blocking to be taken and consideration of where bunks situated to be taken. Additional heating in control stations to be considered. Arrangement to prevent freezing of access doors to be taken. Recommended that provision be made in the arrangement of changing rooms, cabins, lobbies to cabins and public spaces to adequately provide for the stowage and hanging of cold weather clothing. • Accommodation access - Consideration to be given to heating of access arrangements to the accommodation especially the emergency accesses. Alternatively arrangements can be provided to break initial seal. Means to keep access ways clear to be provided. • Intake and exhaust louvers - All intake and exhaust louvers for accommodation and machinery spaces shall be provided with means to prevent snow blockage or icing. • Pilot boarding - Each vessel will require an ice pilot when transiting the ice. A combination of pilot ladder and accommodation ladder is required for safe transfer of pilots from a icebreaker or launch. Operation of the pilot boarding arrangement to be suitable for -25°oC with 20ms-1 wind speed. A helicopter winching area meeting the requirements of IAMSAR (International Aeronautical Maritime Search and Rescue) manual and ICS (International Chamber of Shipping) Helicopter/Ship Operations is also to be provided for emergencies. Means to keep the winching area and pilot boarding area clear of snow and ice to be provided. 8 Weather 8.1 Weather Conditions The general weather in Aniva Bay is good with the terminal being sheltered from all directions other than the South-West. The wave and currents are more wind driven than under oceanic influence. 8.2 Weather Seasons The area is subject to two weather seasons: • Summer Season May – September This is a warm period with winds from all directions. The wind force is typically less than 12 m/sec, although this can be 0000-S-90-01-P-0207-00-E Page 25 of 101 BM Code: EP.14.03.01.09
