Lorengau, Papua New Guinea

Lorengau: Submarine Cable Landing Point

Lorengau is the major town of Manus Province, Papua New Guinea, situated on the edge of Seeadler Harbour on Manus Island in the Admiralty Islands. As an island community, its connection to submarine cable infrastructure provides an important link to the broader national network. One submarine cable lands at Lorengau, connecting it to the domestic and regional cable system that extends across Papua New Guinea and into Indonesia.

The single cable serving Lorengau is the Kumul Domestic Submarine Cable System, a substantial system that enables connectivity across the island groups and provinces of Papua New Guinea while also reaching into Indonesian territory. Its presence at Lorengau places Manus Island within the national submarine cable grid, supporting the inter-island corridor that this system was designed to serve.

Cables Landing at Lorengau

The Kumul Domestic Submarine Cable System is the sole submarine cable landing at Lorengau. The system spans 5,457 km in total length and reached ready-for-service status in 2019, with its current status noted as draft. In addition to Lorengau, the cable connects multiple landing points across Papua New Guinea and extends to Indonesia, making it a domestic and regional inter-island system. It is the primary mechanism by which Manus Island is integrated into the submarine cable infrastructure shared across Papua New Guinea's dispersed island geography.

Regional Context

Within Papua New Guinea's submarine cable landscape of 15 landing points, Lorengau sits alongside several single-cable landing points including Alotau, Arawa, Daru, and Kavieng, each also served by one cable. Port Moresby leads the country with four cables, while Madang hosts two, reflecting the concentration of cable infrastructure in larger urban and coastal centres. Lorengau's position among this group of single-cable landing points places it in the majority tier of Papua New Guinea's cable geography.

Network Role

Lorengau functions as a single-cable terminus on the Kumul Domestic Submarine Cable System, serving the inter-island corridor between Papua New Guinea's mainland and outer island provinces, as well as connecting into Indonesia. Rather than operating as a multi-cable hub, Lorengau represents the termination point for Manus Island's integration into this broader domestic submarine network, which at 5,457 km spans considerable distances across the southwestern Pacific and into Southeast Asian waters.

Within the regional submarine cable graph, Lorengau's inclusion on the Kumul system ensures that the Admiralty Islands are not isolated from the national cable infrastructure that links Papua New Guinea's geographically dispersed communities and extends international connectivity toward Indonesia.
