Muroran (JPMUR)

Muroran is the principal industrial port of Hokkaido and a designated port for quarantine and entry. It has the capacity to accommodate vessel up to 280,000DWT and is situated in a natural harbour with depths of 16.5m. The port is divided into three areas: Area No 1 and 2, known as the inner harbour and area No 3, the outer harbour, separated by the Hakucho Bay Bridge.

Summer.

The port of Muroran is situated on the eastern part of Volcano Bay and surrounded by the Etomo Peninsula on the east coast of Hokkaido.

Harbour: LOA 329.95m, beam 57m, draught 16m, 250,950DWT. Offshore: Max draught 16.0m, 115,811DWT.

Approx 14,000,000t of cargo (including 2,400,000t of coal & 2,100,000t of iron ore), 6,000TEU, 40,000 passengers and 4,000 vessels handled annually.

Quarantine anchorage: A quarantine anchorage is established 1.5nm WNW of the harbour entrance. Fish farms are located near this anchorage. The designated anchorage for vessels carrying dangerous cargoes is in Area No 3, holding ground good, seabed generally sand. Good sheltered anchorage can be found in depths of 9.0m. Inner anchorage: The bottom of both inner and outer harbours is mostly sand and provides generally good holding. The inner harbour is well sheltered from winds from N, E and SW, but precautions must be taken against winds from W. Anchorage is prohibited within an area extending S from the inner end of the fairway.

A fairway, depth 16.5m, leads through the harbour entrance under Hakucho Bay Bridge to the first Nippon Steel Berth No 19, maximum draught 16.0m. The alignment 090° of leading lights (42°21.0'N 140°59.2'E) leads: N of No 2 Lightbuoy, moored 0.5nm ESE of the head of South Inner Breakwater and No 1 Lightbuoy, moored 0.6nm E of North Inner Breakwater Light. The alignment 124°06' of leading lights: Front Light (42°20.3'N 140°59.1'E) (aluminium framework tower; red triangle topmark) 17m in height. Rear Light (similar) 22m in height, 0.1nm SE of the front light, leads; between No 3 and No 4 Lightbuoys. Then as required for berthing. Caution: At night, the various leading lights and lightbuoys, and the lights on the breakwaters, are often difficult to distinguish against lights in the background, and the breakwaters are covered at HW. Even in daylight, the large number of vessels in the harbour make it difficult to see very far ahead.

Not compulsory. Harbour pilots board at outer anchorage or approx 1.5nm WSW of the harbour entrance, in bad weather close to the harbour breakwater. For large tanker vessels (VLCC) the pilot boards approx 1nm SSW from the boarding station mentioned above.

The harbour limits extend 1nm NW from Nima Misaki (42°20.1'N 140°55.8'E), then NNE to Poroshireto Misaki.

Chikiu Misaki Light 42°18'N 141°00'E. A Radio Tower (42°19.6'N 140°57.6'E), 214m in height. North Outer Breakwater extends 1.1nm S from Poroshireto Misaki 42°22'N 140° 55'E; a light is exhibited on its head from a white column 14m in height. South Outer Breakwater extends 0.5nm WNW from Daikoku Shima, situated 0.6nm NNW of Nima Misaki. A light is exhibited on South Breakwater head from a red round tower 14m in height; a lightbuoy is moored 0.3nm WSW of the breakwater head. A detached breakwater extends 0.1nm SE from a position 0.15nm WSW of the root of South Outer Breakwater; a light is exhibited from its head. South Auxiliary Breakwater, detached and approx 0.1nm in length, lies in a N-S direction close N of Daikoku Shima. A light is exhibited from the N end of the breakwater. Three breakwaters extend between Daikoku Shima and Nima Misaki; Lights are exhibited on the centre and N breakwaters. North Inner and South Inner Breakwaters lie 1.5nm within the harbour entrance; a light is exhibited on each breakwater head.

Tankers and vessels of more than 30,000t do not normally enter the port at night. Shiratori Ohashi Bridge lies approx 300m E of the outer N breakwater. It spans the fairway between the inner and outer ports districts and has a vertical clearance of 52m.The centre line of the fairway is marked by a white light, the channel edges are marked by red and green lights, exhibited from the bridge. A submarine cable is laid form the E side of Daikoku Shima for 500m SSE to the centre of the breakwater. An overhead cable, vertical clearance 11m, crosses the breakwater opening 700m SSE of Daikoku Shima.

Range: max 1.5m; min 0.1m.

There are 7 tugs available; 3 x 3,200hp; 3 x 2,400hp; 1 x 740hp.

Prevailing winds: SW'ly. Ice: Thin ice forms over shallow areas along the shores, usually in Feb, but very rarely is traffic within the harbour interrupted. The last occurrence causing disruption was reported in 1986. Winds: Strong W winds funnelled into the harbour by the hills rising on its N and S sides, penetrate with unexpected force. After a low pressure system has passed through the area, winds from E often shift suddenly and blow hard from the W.
