Abstract

Offshore scaffolding activities involve high-risk work, especially in deck areas where workers operate at height and near emergency evacuation facilities. Improper scaffolding installation and use may cause structural hazards, workplace accidents, and disruption of liferaft systems. Objective: This study aims to analyze scaffolding implementation in offshore deck areas from the perspective of occupational safety and health. Method: A qualitative descriptive method was used through direct field observation and documentation at the Natuna Forel offshore platform. Data were analyzed by identifying scaffolding components, safety procedures, inspection practices, and potential hazards based on relevant OSH standards and scaffolding guidelines. Findings: The results show that scaffolding implementation generally complied with OSH requirements, particularly in terms of pipe connection, joint position, access system, guardrail installation, PPE use, and inspection procedures. However, a potential hazard was identified in scaffolding installed near the liferaft area, where several pipe ends were not equipped with protective plastic tube end caps. This condition may damage emergency evacuation equipment and reduce emergency response effectiveness. Implications: The findings suggest that offshore scaffolding safety assessment should not only focus on structural stability and worker access but also consider the interaction between temporary structures and emergency facilities. Originality: This study offers a specific contribution by highlighting scaffolding safety in offshore deck areas, particularly its potential impact on liferaft emergency systems, which is rarely discussed in onshore-focused scaffolding studies.

Abstract

Background The bridge compartment of a vessel serves as the primary operational area where navigation and monitoring activities are conducted continuously. Maintaining an adequate thermal environment with in this space is essential to ensure operator comfort, concentration, and operational safety Purpose This study aimed to evaluate the cooling load requirements of the bridge compartment onboard TB. Ananta Sesa 1 and assess the effectiveness of an air conditioning retrofitting strategy in improving thermal comfort conditions Methodology The research employed a field observation approach combined with cooling load calculations using the Cooling Load Temperature Difference (CLTD) method. Findings Internal heat gains from occupants and navigation equipment, as well as external heat gains from solar radiation, wall and roof heat transfer, and air infiltration, were considered in the analysis. The results indicated that the total cooling load of the bridge compartment reached 15,900 BTU/h, exceeding the capacity of the existing 1 PK air conditioning unit rated at 9,000 BTU/h. To address this deficiency, the existing system was replaced with a 1.5 PK split air conditioning unit utilizing R32 refrigerant. Performance testing demonstrated that the retrofitted system reduced the indoor temperature from 36°C to 25.5°C within 60 minutes of operation. The measured relative humidity remained at approximately 55%, which is consistent with thermal comfort recommendations provided by ASHRAE Standard 55 Implications These findings indicate that the retrofitting strategy successfully improved the cooling performance of the bridge compartment and provided thermal conditions that support operator comfort and safe vessel operation Originality The results may serve as a practical reference for cooling system evaluation and retrofit planning in similar marine applications.
