Shore power for tankers has a significant potential to reduce in-port emissions

Shore power for tankers has a significant potential to reduce in-port emissions

As part of a CEF Study project co-funded by the European Union, the Port of Rotterdam, in collaboration with the municipality of Rotterdam and various partners, is conducting four feasibility studies for shore power. These studies are being conducted at four major terminals in the port of Rotterdam: the ECT (Amazonehaven), APMT2 (Amaliahaven), VOPAK (Vlaardingen), and the Cruise terminal (Wilhelminakade). The studies encompass detailed technical analyses, environmental and social cost-benefit evaluations, and the preparation of tendering and permitting procedures.

Feasibility Study for Liquid Bulk

The study for Vopak Vlaardingen, undertaken in consortium with Vopak and Stolt Tankers, aims to establish a global standard for shore power for tankers. Between 2022 and 2024, the Port of Rotterdam, Vopak, and Stolt Tankers conducted a preliminary technical feasibility study, a business case analysis, and a preliminary environmental impact assessment.

DNV Maritime Advisory was engaged to identify various technical solutions for the ship-shore interface for shore power for tankers and assess these solutions’ safety and operational implications. In June 2023, DNV completed a preliminary technical feasibility study on developing a high voltage Onshore Power System  for tankers. The study included:

  1. An in-depth investigation into current shore power solutions for tankers, addressing challenges like grid power availability, frequency, voltage level, and load requirements for different tanker types.
  2. Evaluation of three OPS connection scenarios:
    • Scenario 1: Midship connection using the ship’s crane for the OPS cable.
    • Scenario 2: Midship connection with a crane-based Cable Management System on the jetty.
    • Scenario 3: Stern connection with a crane-based CMS onshore or on a platform/monopile in the water.
  3. A Safety assessment identified scenario 3 as the safest, with no high-risk hazards, compared to four and three high-risk hazards in scenarios 1 and 2, respectively.
  4. In a Multi Criteria Analysis, scenario 3 was preferred due to superior safety, operability, technical maturity, and equipment availability.

OCIMF and Shore Power Standardisation

During the development of the preliminary technical feasibility study, consortium representatives engaged with the Oil Companies International Marine Forum. As a result, OCIMF has begun working on guidelines for shore power for tankers and has published preliminary design recommendations. This collaboration is expected to aid further standardisation by the IEC/IEEE/ISO.

Financial, Environmental, and Social Impact Analysis

Rebel Ports & Logistics assessed the financial, environmental, and social impacts of installing shore power at Vopak Vlaardingen. Completed in April 2024, the study highlighted significant emission reduction benefits, improving air quality and public health. However, the financial analysis revealed a substantial viability gap, necessitating project optimisation and potential subsidies to bridge this gap. Regulatory measures may also be needed to encourage the uptake of shore power by tankers.

Next Steps

Port of Rotterdam, Vopak, and Stolt will continue striving for the standardisation of shore power for tankers and aim to facilitate a demonstration project at Vopak Vlaardingen. The next phase of the project includes:

  • Executing a preliminary design for the shore power installation at Vopak Vlaardingen.
  • Engaging important clients from Vopak and Stolt Tankers at the Vlaardingen Terminal.
  • Engaging with potential subsidy providers on their participation in the project.

Additionally, the Port of Rotterdam, Vopak, and Stolt will organise two information events in the third quarter of 2024, one for Rotterdam-based partners and one for international partners.
