Resorts World Sentosa banks on Oceanarium to attract large crowds
The revamped Singapore Oceanarium, formerly known as the S.E.A. Aquarium, will reopen to the public on 23 July 2025, following nearly three months of renovation works. Located on Sentosa Island, the facility is now three times larger than its predecessor. It aims to offer visitors a more immersive and educational exploration of marine life and ocean conservation.
Announcing the development on 26 May, integrated resort operator Resorts World Sentosa (RWS) described the transformation as more than a rebranding. The n as a “world-class ocean institute” focused on marine education, scientific research, and sustainability.
Ocenarium divided into 22 zones
The attraction will feature 22 themed zones, guiding visitors through various marine habitats — from shallow coastal waters to the deep sea — and spanning periods from the prehistoric era to the present day.
Among the key exhibits is Ocean Wonders, home to one of the world’s largest kreisel tanks, specially designed to house delicate marine species such as jellyfish. This exhibit will showcase thousands of moon jellies in a visually striking display.
Another exhibit, Singapore’s Coast, highlights native biodiversity through mangrove-inspired settings and interactive habitats, offering insights into the country’s natural marine environment.
In the Open Ocean zone, visitors will be able to view reef manta rays and zebra sharks swimming alongside thousands of other marine animals, all visible through a massive 36-metre-wide viewing panel — one of the largest of its kind. In support of its expanded educational mission, the Singapore Oceanarium is partnering with top academic institutions.
Revamp under financial strain
The revamp also comes amid a challenging financial backdrop. In 2024, RWS, operated by Genting Singapore, remained profitable but saw its net earnings fall by 5 percent to SG$ 578.9 million (€393 million).
The second half of the year was particularly difficult, with earnings dropping 34 percent year-on-year to SG$ 221.96 million (€151 million), despite a 5 percent increase in annual revenue to SG$ 2.53 billion (€1.72 billion). The decline was attributed to rising operating costs and inflationary pressures.
Adjacent to the oceanarium will be a newly built research and learning centre, featuring immersive labs, seminar rooms, collaborative workspaces, and a rooftop event space. The facility aims to boost marine science outreach and public engagement.
“This new oceanarium is not just a destination, but a catalyst for change,” said Tan Hee Teck, CEO of RWS. “It is a place where curiosity transforms into knowledge, and knowledge into real action.”
Details on ticket prices and programmes are expected to be announced on 27 May 2025 at 3 pm (SGT).
