Understanding Dry Dock Compliance in Indonesia

Indonesia's maritime regulatory framework mandates regular dry docking for vessel classification maintenance, statutory certification, and seaworthiness verification. Under SOLAS regulations, all merchant vessels must undergo complete hull surveys in dry dock twice within every 5-year period, with intermediate surveys within 36 months maximum. The Directorate General of Sea Transportation (DGST) enforces these requirements through Port State Control inspections, while Biro Klasifikasi Indonesia (BKI) serves as the national classification society providing classification and statutory survey services. Our platform offers comprehensive marine inspection services including dry dock planning tools – start your free trial today to ensure systematic preparation meeting both Indonesian national requirements and international convention standards.

SOLAS Survey Requirements
The International Convention for Safety of Life at Sea mandates complete hull surveys in dry dock twice within every 5-year period for cargo vessels. The interval between any two dry dock inspections cannot exceed 36 months. Passenger vessels require annual bottom inspections, with two conducted in dry dock within each 5-year period. Classification societies may offer Extended Dry Docking (EDD) schemes extending intervals to 7.5 years for eligible vessels meeting strict criteria including age under 10 years and high-quality coatings.
BKI Classification Surveys
Biro Klasifikasi Indonesia, as an IACS member, conducts classification surveys including class renewal (every 5 years), annual surveys, intermediate surveys, and docking/bottom surveys. Indonesian-flagged vessels must maintain BKI classification to operate legally in Indonesian waters. Survey requirements cover hull structure inspection, thickness measurements, propeller shaft examination, rudder bearing clearances, and sea valve inspections under Law No. 17/2008 on Shipping.
Tokyo MOU Port State Control
Indonesia achieved White List status under Tokyo MOU, demonstrating compliance excellence for vessels operating in Asia-Pacific waters. Port State Control Officers verify dry dock survey completion and certificate validity during inspections. Detention rates in the Tokyo MOU region hover around 2-3%, with ships having five or more deficiencies facing high detention probability. Proper dry dock preparation prevents deficiencies affecting vessel trading across 21 member countries.
Statutory Certification
Dry docking provides opportunity to complete surveys for Safety Construction Certificate, Load Line Certificate, and International Oil Pollution Prevention Certificate renewal. BKI, as a recognized organization for Indonesia and Mongolia, issues statutory certificates on behalf of flag state administrations. Survey timing must align with certificate validity windows – typically 3 months before expiry to certificate date.
Critical Compliance Warning:

Failure to complete required dry dock surveys within mandated intervals results in class suspension, certificate invalidation, and potential vessel detention. Ships with suspended class face insurance coverage issues, port state control targeting, and prohibition from trading in major ports. Plan dry docking 6-9 months in advance to secure preferred shipyard slots and complete all required surveys within the compliance window. Indonesian shipyard capacity varies seasonally, with high demand during favorable monsoon periods requiring early booking.
